Setup
Switch 10: Stack Mode
Normally set to the DOWN position (Stack Mode disabled). This switch, when set UP, enables the
controller to look at the communication on the network—allowing multiple controllers to be stacked
in parallel for larger systems. With more than one networked controller in the system, set this
switch UP (enabled) on each controller in the system, to allow the charging parameters in all the
controllers to be synchronized.
Info:
If Stack Mode is enabled (DIP switch 10 set UP), each networked controller in the
system must have a unique and valid controller address number. Use DIP switches 7,
8 and 9 to set a different and valid address number (C01 to C07) for each controller.
Note:
If DIP switch 10 is UP (stack enabled) and DIP switches 7, 8, and 9 are in the
DOWN position, the address shows as C00. Controller address number C00 is not a
valid address number and must be changed to communicate to other controllers.
Switches 7, 8 & 9:
When DIP switch 10 is in the (normally) DOWN position, DIP switches 7, 8, and 9 determine the
absorption charge time of the PT controller. However, if DIP switch 10 is set to the UP position, it
enables Stack mode and allows the PT controller to be networked (i.e., connected to a Magnum
inverter and remote). Once the PT controller is networked, the absorption time is now determined
by the remote; and DIP switches 7, 8, and 9 are now used to determine the address number of the
controller. If multiple controllers are stacked together, a unique and valid address number (C01 to C07)
for each controller is required. See Sections 2.11 and 4.13 for information on stacking controllers.
Absorption Charge Time
When the PT-100 controller is NOT networked, eight (8) time periods are provided to determine
how long the controller is in the Absorption Charge stage—holding the batteries at the Absorb
Voltage setting. The Auto Time Detection setting (switches 7, 8, and 9 are all set to the DOWN
position) uses an absorption time that is equal to the time it takes the batteries to reach the Absorb
Voltage setting while in the Bulk Charge stage. So if the battery is heavily discharged and it takes
a long time to reach the absorb voltage, the same time will be used to keep the batteries in the
Absorption Charge stage. The other seven (7) DIP switch settings can be used to provide a known/
fi
xed absorption time period from 1 hour to 7 hours.
